GE DS200VPBLG2A
Product Introduction
Precise signal conditioning is the foundation of safe and efficient turbine operation. The is a critical analog I/O board within the Speedtronic Mark V ecosystem, specifically designated as the TCQA board. It is responsible for scaling and conditioning a wide array of analog signals from the turbine’s field instrumentation before they are processed by the core controllers.
This board handles everything from LVDT position feedback and servo valve outputs to thermocouple inputs and 4-20mA process signals like compressor stall detection and fuel flow pressure. Field engineers specify the because its robust signal conditioning ensures that critical control loops receive clean, accurate data, even in the electrically noisy environment of a power generation facility.
Key Selling Points & Differentiators
- Native Mark V Compatibility: Designed specifically for R1, R2, and R3 cores in the GE Mark V system; not recommended for Mark VI or non-GE platforms due to proprietary VME bus architecture.
- Comprehensive Signal Conditioning: Handles LVDT, servo valve, thermocouple, 4-20mA, vibration, and pulse signals on a single board, reducing cabinet footprint and wiring complexity.
- Hardware-Configurable Outputs: Features jumpers (J1, J2, J5, J6) for selecting and configuring milliamp output circuits, allowing field customization without firmware changes.
- Rigorous Live Bench Testing: Every unit undergoes a 24-hour continuous load test with multi-signal simulation and VME bus communication verification before shipping.
- New Surplus Availability: Factory-sealed condition with verified source traceability, bypassing typical OEM lead times for discontinued Mark V hardware.
- Anti-Counterfeit Verification: Serial numbers are checked against manufacturer databases during incoming inspection to guarantee authenticity.

FAQ
No. The is designed exclusively for the Mark V platform. Mark VI systems use a completely different I/O architecture and do not support the TCQA board form factor or VME bus. Always verify your system generation before ordering.
I have a DS200VPBLG2B on hand. Can I use it as a direct replacement?
The suffix (G2A vs. G2B) often indicates hardware revisions, jumper configurations, or specific signal conditioning calibrations. While they may be functionally similar, mixing revisions in a redundant core can cause signal scaling mismatches. Always match the exact suffix or consult the Mark V hardware manual for approved substitutions.
Do I need to configure the jumpers before installing?
Yes. The board requires hardware jumper configuration for milliamp output circuits (J1, J2) and current range selection (J5, J6). J7 is used for RS232 card testing, and J8 starts the oscillator. I always recommend verifying the jumper settings against your existing board or system manual before installation to ensure correct signal scaling.
What signals does this board condition?
The (TCQA) conditions LVDT inputs, servo valve outputs, thermocouple inputs, 4-20mA inputs/outputs (including compressor stall detection and fuel flow pressure), vibration inputs, relay driver outputs, pulse inputs, voltage inputs, and generator/line signals. Refer to the Mark V I/O manual for the complete signal list and terminal assignments.
Is there a warranty on this new surplus unit?
Yes. All new surplus modules come with a standard 12-month functional warranty. If the unit fails during normal operation within that period, we provide a direct replacement. We also include our internal test report with every shipment so you can verify the 24-hour load test and signal conditioning results before installation.
